The Hound of the Baskervilles Chapter 12 Summary

Summary

Watson, having hidden in a hut, is startled when Sherlock Holmes unexpectedly reveals himself outside; Holmes has been working secretly on the case and explains his reasons for concealment and the steps he has taken, including bringing Cartwright to assist him. They sit in the hut as Watson recounts his recent interview with Laura Lyons. Holmes interprets that Mrs. Stapleton is actually Stapleton's wife and not his sister, and he explains how investigations into the naturalist's past identify him as a former schoolmaster with a mysterious vanished school and a missing wife. Holmes lays out the stakes: he believes Stapleton is committing deliberate murder, that their nets are closing, and urges Watson to guard Sir Henry closely for a day or two while they finish gathering proof.

While they speak dusk becomes night and suddenly a horrifying scream rends the moor. Holmes and Watson run toward the sound across the difficult terrain, hearing another agonized cry and then a dull fall. They find a body face-down among rocks; at first they think it is Sir Henry, but a match reveals the dead man has a beard — it is Selden, the convict. From Watson's recollection that Barrymore had passed Sir Henry's clothes to aid Selden's escape, the detective and Watson deduce Selden was wearing Sir Henry's garments and therefore was pursued by the hound. The tragedy is double-edged: Selden's death is both a terrible event and a grim clarification of the hound's method. Stapleton appears at the scene, offers an explanation that Selden died from exposure and fright, and escorts himself away. Holmes insists they cannot yet arrest Stapleton: they lack provable evidence connecting him to the hound and to Sir Charles's earlier death. They carry Selden into a hut for the night and resolve to press on with their investigative plan, particularly involving Laura Lyons, while maintaining the necessary secrecy around Sir Henry.

Analysis

This chapter shifts the novel from investigation and conjecture to violent, tangible consequence: death on the moor forces the abstract horror of the legend into physical reality. Structurally it reunites Holmes and Watson in the field (Holmes now acting covertly), advances key revelations (Mrs. Stapleton is actually Stapleton's wife) and narrows the circle of suspicion toward Stapleton. The chapter uses contrast: Holmes' cool intellect and ironic manners set against the raw panic of the moor; the calm, almost theatrical unmasking of facts is followed by a primal scream and the chaotic, frantic chase. The moor itself remains a character — its darkness, silence, and treacherous terrain amplify suspense and echo themes of isolation and nature's indifference.

Symbolically the hound functions as a mechanized instrument of human malice rather than a supernatural force, and Selden's death in Sir Henry's clothes literalizes the theme of identity and substitution. Narrative technique blends detective exposition (Holmes explaining prior research) with immediate third-person action and sensory detail at the discovery scene, maintaining atmospheric tension. The chapter also tightens moral complexity: while Selden is a criminal, his death exposes the deliberate cruelty behind the hound plot, intensifying Holmes's moral urgency but also his frustration at lacking admissible evidence. Finally, Stapleton's composed, opportunistic presence at the corpse scene underscores his nerve and cunning, heightening suspense about his next moves and framing the investigators' dilemma: acting now risks losing the case by lack of proof, while waiting risks further tragedy.
